As vice president under the ailing General Ahmed Hassan al-Bakr, and at a time when many groups were considered capable of overthrowing the government, Saddam created security forces through which he tightly controlled conflict between the government and the armed forces. In the early 1970s, Saddam nationalized oil and other industries. The state-owned banks were put under his control, leaving the system eventually insolvent mostly due to the Iran–Iraq War, the Gulf War, and UN sanctions. Through the 1970s, Saddam cemented his authority over the apparatuses of government as oil money helped Iraq's economy to grow at a rapid pace. Positions of power in the country were mostly filled with Sunni Arabs, a minority that made up only a fifth of the population.
